well, 3 normal forms is the ideal - but we live in a real world. So after normalising the database, it is often found that repeating a field, or adding a field that can be calculated from existing fields in a table speeds up things enormously without significantly compromising database integrity. So we do it. It may not be necessary in a smaller database, but may be needed in a bigger one. -- regards KG http://lawgon.livejournal.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
